INSULATOR.

SPECIFICATION forming part of Letters Patent No. 574,828, dated January5, 1897.

Application filed March 10, 1896. Renewed December 14, 1896. Serial No.615,713. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN DU BOIS SMOOK, a citizen of the UnitedStates, residing at WVickatunk, in the county of Monmouth and State ofNew Jersey, have invented oertain new and useful Improvements inInsulators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to a certain new and useful improvement ininsulators for the support of electric wires and the like, and it hasfor its object, among others, to provide a simple and cheap insulatorreadily applied and still by which the wires will be securely and firmlyheld and from which they cannot become accidentally displaced. Myinsulator is designed to be used either upon the upper end of a pole orother support or from a suspending device of any sort.

The invention is capable of embodiment in various forms, some of whichonly are herein illustrated. The insulators may be made of variousshapes and sizes.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a perspective view of one formof my improved insulator. Fig. 2 shows the same form supported upon theupper end of an upright. Fig. 3 is a view of the wedge employed.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates theinsulator, of glass or other suitable material, preferably substantiallycone-shaped, as shown, and as seen in Fig. 1 it is formed with a hole Bfor the reception of the hook G or hanger, which may be suspended fromany suitable support. The

insulator is further provided with an opening D for the reception of thewire E, and this opening has an inclined outlet F, through which thewire may be introduced, and, further, with an opening a, through whichthe anchorflvire B may be passed, and the ends thereof wound upon thewire E, as shown. After the wire E is in position it may be securedagainst accid ental displacement in any suitable manner. I have shown awedge G, which is provided with ribs g, adapted to enter correspondingrecesses or grooves in the opposite walls of the inclined opening in thebody portion of the insulator. For further security the wedge is shownas provided with an opening 9, through which and an opening a in thebody portion of the insulator may be placed a wire G to fasten the wedgein place. WVhen the insulator is to be used on a pole or other support,as seen in Fig. 2, the opening or hole B is dispensed with, and in thelarger end of the body portion is formed an opening into which thesupport X may beinserted. This opening may be screw-threaded, ifdesired. The insulator is used in an inverted position from what it iswhen suspended from a hanger, as will be readily understood.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages. Thefacility with which the device may be attached to a cross-tree isimportant. It may be readily attached by a double hanger-pin,

and permits the use of lighter poles, a diminished number ofcross-trees, and facilitates the unhooking and repairing.

What is claimed as new is 1. An insulator consisting of a body portionwith an opening to receive a wire and a ribbed wedge adapted to beinserted to hold the wire therein, as set forth 2. An insulatorconsisting of abody portion with an opening with inclined outlet havinggrooves, and a removable wedge having ribs fitted to said grooves,substantially as specified.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

BENJAMIN D. B. SMOOK.
